Corn and millet intercropping method

Abstract

The invention relates to a corn and millet intercropping method. According to the intercropping method, an intercropping ridge ratio of the corn and milet is 1:1.5, and three rows of the millet are sowed in each ridge; two rows or three rows of the corns are sowed in each ridge; and the millet or corns in each ridge of a land can be planted in a dog bitten grain mode. By the method, a traditional mode of planting corns in a large region is broken, high-stem crops and low-stem crops are planted on the land in a combined manner, so that a height difference is formed, and the crops are good in ventilation, and resist wind and lodging; and moreover, the corns can keep out the wind, relieve cold and shade the sun for the millet. By the intercropping method, the yield of the corns is the same with that of the corns planted by the traditional mode of planting the corns in the large region, but 0.4 hectare of millet is harvested in each hectare of the land, limited land resources are utilized better, and the purpose of increasing both production and income of farmers is achieved.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for intercropping corn and millet. Background technique [0002] Corn is an important food and feed crop. Because of its high yield and simple field management, it has been planted in a large area in my country, especially in Northeast China. Corn has been the main crop. Now farmers are planting corn in large areas, and they are planting densely. They just leave an empty ridge in the middle of five or six ridges for ventilation. Due to poor ventilation, the ears of corn are small, and the light transmission is not good. The empty ridges caused waste again, so that the limited land is not better utilized. Millet is rich in nutrients needed by the human body, but due to its low yield, fewer and fewer farmers have planted it in recent years. Contents of the invention [0003] The purpose of the present invention is to provide a corn and millet intercropping planting method...
